The Observations of the former we shall here declare, as he presented them in writing to the R. Soc. the 17th of December 1668, which was as follows;
YOu may remember, that about 3. weeks since I brought the Testiculos Cuniculorum marium dissected in several shapes; which appear'd to several or this illustrious Company, as well as to my self, to be indeed made up of Vessels; and I then had particularly show'd them to M. Hook and some others, and the manner how they lay; who seem'd to be fully satisfied by the help of a good Glass, they then made use of. And being, desired, to give in the Account in writing, I cannot but affirm here, that I find the Vessels in the Testes of this kind of Animals to lye in round folds, in the manner of the little intestins, but both ends of each roll meeting at their insertion, which seems to be made into the Ductus Nervosus: And every one of these little rolls are very curiously embroidered with other vessels, which I Judge to be Veins and Arteries by reason of their reddish colour; appearing in them even to the bare Eye.
These little rolls ly in ranges, having a kind of vniformity not unpleasant to behold by a good light. But I do not mean, that every one of these rolls is one entire tube, but consists of many tubes, besides the said Embroidery of Veines and Arteries: For, when I cut one of the said rolls transverse, there seem'd to me (and so, I suppose, will it do to any, that think it worth examining,) 5. 6. or more distinct tubes in one roll, contain'd as 'twere, in one common membranula; but the fine texture and tenderness of them is such, that they will not admit of expansion in such a manner, as some other Testes will, and especially as that of a Ratt is said to doe by Dr deGraeff
